TYPEGASTING MECHANISM FOR LINOTYPE-MACHINES.

Specification of Letters Patent.

Patented Dec. 4, 1917.

Application filed September 21, 1915. Serial No. 52,955.

To all whom it may concern.

Be it known that I, GEORGE E. MAnLA'r'r, a citizen of the United States, residing at Pasadena, in the county of Los Angelcs and State of (Jalifornia, have invented a new and useful TypeCasting Mechanism for Linotype-lvlachines, of which the following is a specification.

My invention relates to slug casting mechanism for typographical machines and'particularly to a device insertiblc in the casting slot of the mold for regulating the length of the type slugs. My improved device is adapted to be used in connection with the usual liner plates which are movable in the mold slot for forming ends for the slot, said liner plates bein of diiierent lengths and different liners ein used for different lengths of slugs. With the improvements hereinafter set forth in detail, it will be possible to produce type slugs of variable length, the liners being set to correspond to any desired length of slug thereby. Other ob]ects may appear as the description prog resses.

Referring to the drawings, Figure 11s a Ian of the mold showing my liner placer lnstrument in position therein; Fig. 2 is a sectional elevation of the same on the line 2-2; Fig. 3 is a sectional elevation on the line 3-3; Fig. 4 is a partial front elevation; Fig. 5 is a fragmentary section of Fig. 1 on the line 5-5; Fig. 6 1s a perspective view of the locking wire; F ig.'7 is an end e1evation of Fig. 1 detached from the mold; Fig. 8.is a perspective view of the liner plate; and Fi 9 1s a perspective view of the mold cap. gimilar-characters ;of 'reference' are used in the specifications and the several views of the drawing for indicating the same parts. y

The liner placer instrument comprises an index bar 1 having a stationary head 2 secured thereto consisting of a top plate with outwardly projecting arms Band 4 formed thereon and the end piece 5 provided with a recess 6 on the inner side in which a plug 7 is pivoted and a spring 8 is held for, action against the plug. The plate is secured to the bar 1 by means of screws 9 and the top of the bar 1 has a plurality of rectangular grooves 15 formed therein and numbered from 1 to 30 inclusive, the numerals re re senting ends of length and correspon mg with the scale on the assembler slide of the machine.

A lock 10 is slidably held on. the bar 1 and has a top plate 11 which is held bymeans of screws 12 on the body 13 and has grooves 14 formed on its upper surface, these grooves being arranged in pairs and register with the grooves 15 on the bar 1, and are so spaced that one pair will register ems and the other pair half ems. A lunger pin 16 is carried by the forward cm of the body 13 and is provided with the enlarged head 17 which slidable in the body bore 17, the stem 18 being slid-able in the smaller bore; 19 and the outer end of the stem 18 being secured to the head 20. A spring 21 is carried on the stem 18 is compressible between the bottom of the bore 17 and the head 17 of the plunger for holding the head 20 normally against .the body 13. The head 20 may be moved outwardly from the body 13 by compressing the spring when the plunger is moved through the body.

.A double pronged locking wire 22 slidably engages thegroove 14 of the body and those 15 of the bar 1 for holding-the lock 10 in any desired position on the index bar 1.

of the plunger and The outer ends of the grooves 14 are slightly by notchin the ends of the wire, so that when the wire 22 is pulled forward the shoulders 24 on the wire will engage those in the grooves and ordinarily prevent the wire from being withdrawn from the body.

The plate 11 of the lock 10 has an extended arm 25 which is provided with a notch and shoulder 26, of a shape to conform to the edge of the liner 27 as shown in Fig. 1, the liner being pressed into position in the lock 10 between the arm-25 of the plate 11 and the plunger head 20, and thus held by the tension of the spring 2].. The right hand liner 27 which engages the arm -3 of the head 2 serves for establishing the position of the instrument in the mold, and the plug-7 I having the rib cells 29 forme on its lower surface. The pins 30 and 31 serve to hold the mold base and cap in alinement. The plate 32 which has a notch 33 formed thereon at one end for engagcn'ient with the pin 30 of the mold and the notch 34 at the other end for engagement with the pin 31, provides a casting surface different from that of the mold cap 29, under which it may be used.

In operation, this instrument, when inserted in the casting slot of the mold, as shown in Fig. 1, either with or without the plate 32, and the lot-l: 10 set in a desired position, on the index bar 1 to ft'ii lsi'fl l'itl to the length of the type slugs plfitlllt'ctl, serves as a positive means for eli'ecting the placement of the liners 27 and 27 to correspond to the scale on the index bar. been set in the proper places the instrument may then be withdrawn from the mold. The space. in the mold to the left of the liner 2? may be filled with type metal in the cast-- ing operation after the liners have been placed and secured in the usual manner, and the type slugs are then cast in the space between the liners 27 and 27.

The liner 27 provides a greater range of adjustment than is possible with usual form and the pin 35 ordinarily prevents the liner from being placed with reference to the last few g'raduations of measurement indicated 011 the scale, and a groove 37 is therefore provided on the lower surface of the liner so that the liner may clear the pin 35 on the mold. This groove as shown in broken lines in Fig. 1, also serves to receive the cast of metal which flows therefrom into the opening 38, unites with the liner, and thus firmly establishes the position of the liner in the mold.

Having thus described my invention, what I claim is 1. A liner placer for typographical molds comprising a line measuring scale capable of being held at one end in contact with the stationary liner provided With means adjustable to varying distances from said end for holding and regulating a placement of the movable liner whereby to fix the space between the liners so as to conform to the desired lengths of the slugs produced thereb 2. -A typographical machine liner 'placer comprising an index bar having a scale formed thereon, means on said index for engagement with a stationary mold liner, and adjustable means for supporting the movable liner and for setting said iner at desired points to produce type slugs of varia-' ble length.
